At the Arnold Aboretum near Boston Professor Sargent says 

 it is perfectly hardy and free flowering and "is eertainly one -of 

 the most valuable single roses which has lately been introduced 

 into gardens. "t 



It seems entirely fitting that to Dr. W. H. Van Fleet, the orig- 

 inator of the Silver Moon and the Van Fleet roses, those master- 

 pieces of rose hybridization, should be given the credit for in-* 

 sisting, as long ago as 1907, that Rosa hugoiiis be introduced into' 

 America for the dooryards of American homes and for the use 

 of American rose hybridizers. It was his insistence that led the 

 Department of Agriculture to import it from Kew Gardens. 



In the photograph Rosa hugonis is shown as espaliered against 

 the wall of the writer's house at North Chevy Chase, Md. Every 

 spring, before anything but the Japanese flowering apricots (Pru- 

 niis mumc) and the single flowering Japanese cherries are in 

 blood, it has delighted all who have seen it, but even in winter it 

 is ornamental because of its red-brown stems, red thorns and its 

 picturesque growth. ■ 



When not trained against a fall it grows to a height of about 

 5 feet and its stems are clothed with numerous slender spijnes 

 which are bright red on the straight young shoots. Its leaves 

 are thin and delicate and so far as the writer's observations go it' 

 is not subject to the rose spot disease which turns briar rose ' 

 bushes, such as Lord and Lady Penzance, into long unsightly 

 masses of naked stems before the summer is over. 



This lovely yellow rose has one small drawback. It does not 

 seem to grow easily from cuttings or slips. It seeds freely, how- 

 ever, and can be raised in this way even should a quicker way; 

 not be discovered. 



To those who are interested in roses it may be a matter of 

 satisfaction to know that the breeding of this rose with others' 

 is now going on here in America, and the appearance of some' 

 new descendant of Father Hugo Scallan's rose is probably merely 

 a matter of time. — Journal of Heredity for Scptcmher, \9\S. 



GREAT IRRIGATION DAM. \ 

 I 



The Arrowrock dam near Boise, Idaho, is practically com-' 

 plcted and has been in service during the irrigation season of 

 1915. This dam provides stored water for use in the irrigation 

 of lands adjacent to Boise, Nampa, Caldwell and other towns 

 within the limits of the Boise Project of the United States Rec- 

 lamation Service. 



The Arrowrock dam is the highest in the world, having a 

 height of 348.5 feet from the lowest jKjint in the foundation to 

 the top of the para]K't. It is 1100 feet long on toj), contains 

 585,200 cubic yards of concrete and its crest carries a roadway
